The criminals who change or delete data, or who deliberately gobble largeamounts of computer resources, have a more sinister motive and arecapable of doing immense damage.

Avoiding Harassment and Phishing

Of course, there is always the possibility that a computer voyeur will"accidentally" bumble around an unfamiliar system and cause appreciabledamage to someone else's files or programs.

"The tools are super fast and easy to use - I use them every time I write. Thank you."- Mark T.

A hacker designing a malicious program to use a victim's e-mail address bookor document files could simply assume that the victim used the defaultlocation for these files.

Or it can be used in long distance communication throughmodem.

Sometimes there’s a fair amount of data—or code—that’s needed to set up a particular computational essay. The cloud is very useful for handling this. Just deploy the data (or code) to the Wolfram Cloud, and set appropriate permissions so it can automatically be read whenever the code in your essay is executed.

Legislatures chose to enact totally new statutes.

OK, so if a computational essay is done, say, as homework, how can it be assessed? A first, straightforward question is: does the code run? And this can be determined pretty much automatically. Then after that, the assessment process is very much like it would be for an ordinary essay. Of course, it’s nice and easy to add cells into a notebook to give comments on what’s there. And those cells can contain runnable code—that for example can take results in the essay and process or check them.

The technology of Wolfram Notebooks makes it straightforward to put in interactive elements, like , into computational essays. And sometimes this is very helpful, and perhaps even essential. But interactive elements shouldn’t be overused. Because whenever there’s an element that requires interaction, this reduces the ability to skim the essay.

Would it be reasonable for someone to walk around in the parking lot, letting some air out of tires, so tires are seriously underinflated, with the justification that the ensuing accidents will call attention to the problem of underinflated tires?
